Steve Yeom commented on HIVE-18619:
-----------------------------------
Note that session based temporary table is only visible to its session.
Thus there is no possible issues in Concurrency and Isolation.
> Verification of temporary Micromanaged table atomicity is needed

> Session based temporary table by HIVE-7090 had no consideration of
> Micromanaged table
> (MM) since there was no insert-only ACID table at its creation tije.
> HIVE-18599 addressed the issue of no writes during CTTAS (Create Temporary
> Table As Select)
> on Micro-Managed table. But atomicity of temporary MM table is not verified.
